stolen-from-head_libata-updates.dpatch

When we pulled it in, we believed it was from linus head tree but it was instead from
ata-dev. The author of the patch told us that it is dangerous even if the bug report
asking for it says otherwise.

https://bugzilla.ubuntu.com/show_bug.cgi?id=6109

The 2 modules are:

SCSI_ATA_ADMA (ata_adma.ko)
This option enables support for ADMA-standard ATA controllers.

SCSI_PATA_PDC2027X (pata_pdc2027x.ko)
This option enables support for Promise PATA pdc20268 to pdc20277 host adapters.

According to some security guys this delay can cause a very short window of applications
running without cap support. Some of them advocate even that cap should be compiled in
and that the tristate (as module) is pointless, but that goes to the usual religion
believes in terms of security.
Adding the module is harmless, the fix is simply a cp in the right directory.
